Sherlock Holmes Vs Dracula

What do you think of books featuring super-rational Holmes Doyle Dracula cons supernatural? Good fun or an insult? I think Loren D Estleman Sherlock Holmes vs. Dracula and the file of Fred Saberhagen Holmes-Dracula books are well written with good atmosphere of Victorian Gothic, and Doyle did not mind - he left Gillette to make a game where baccalaureate-Sherlock-life falls in love. Thoughts?

Holmes vs. Dracula does not make sense in relation to all the other stories of Sherlock Holmes (I mean real, written by Conan Doyle).

Sherlock Holmes stories have always written something that could happen in real life, even if some of them seemed at first to have a supernatural origin.

For example, the Sussex Vampire was a woman who has been accused of being a step-mother/vampire abuse because she was caught sucking blood from the neck of his step-son, baby. Come and discover it was really saving the life of the child by sucking the poison from his neck over his step-son had poisoned him.

This story looks like it starts with a supernatural explanation, but ended up having a concrete answer to it. Dracula is a fictional character (I'm not talking about the real life of Vlad the Impaler), in order to bring Sherlock Holmes cons would not really pose a mystery Sherlock Holmes style.

And yes, I know Sherlock Holmes is a fictional character, but you get what I mean.

Homes kill Dracula in a minute! :))
